salam!
shyan bhai as i wrote it is not 1000CC car it has a big CC such as 1300 and 1600CCM so it produces more horses and more pick and u cultus is 1000Cc new santro(Atos) is 1100Cc (except in Pakistan) and Toyota Vitz(Yaris) is 1000CC, 1100CC and 1400CcC(D4D)

The Jap version starts with 1300 CC (I think, correct me if I am wrong) and is a great car, Ive heard that Pak Suzuki have imported some cars in Pak and afterwards plan to manufacture it locally (see example of Liana). I have no doubts about the quality of Jap versions and the price tag should be around 10-11 lac for imported ones, but doubt about the ones which will be manufactured here, surely with a reduced price.
About Vitz verses Swift debate, the Vitz we have here are mostly 99-2003 versions, whereas Swift is new, the vitz(european version) was European car of the year in 2000. And it ranks like this (comprison with older Vitz). Reference: 5th Gear site

So you can see that Swift has edge in running costs and value for money. Vitz has edge over swift in comfort,quality and reliability. Keep in mind, when Swift is manufactured in Pakistan, quality would be different, so this comparison is only for Jap made Swift. Hope this clears a lot
